Commit Message

This patch adds generic serial ports over the virtio serial bus.
These ports have a few more options that are not relevant for
virtio console ports: the ability to cache buffers that are
received for a port while it's disconnected, setting of limits
to the bytes that are cached so as to prevent OOM conditions,
etc.
Sample uses for such a device can be obtaining info from the
guest like the file systems used, apps installed, etc. for
offline usage and logged-in users, clipboard copy-paste, etc.
for online usage.
For requirements, use-cases, test cases and some history see
